STOP-AND-WAIT & CONTINUOUS ARQ 1. Consider the use of 5000 bit frames on a 1 Mbps satellite channel which has a propagation delay of 250 ms. (a) How much time is required to transmit a single frame? [5 ms] (b) If each frame is explicitly acknowledged by the receiver (i.e., the receiver returns a separate acknowledgment for every frame it receives), what is the maximum link utilization for: i) Stop-and-wait ARQ? [0.99%] ii) Continuous ARQ with a window size of 7? [6.93%] iii) Continuous ARQ with a window size of 255? [100%] 2. Assume that device A has an infinite number of 9600 bit frames ready to be transmitted to device B, that the transmission rate is 400 kbps, that the propagation delay from A
